Scientists have worked out how to bring beams of light to a screeching halt inside a material that would separate the light into its constituent colors, creating a rainbow—a trapped rainbow.
To bring light to a stop from its usual approximately 670 million mph (1.08 billion km/h) pace is no easy feat, and scientists have been working on the problem for years in hopes of revolutionizing how information is stored and sent.
To tackle the challenge, physicist Ortwin Hess of the University of Surrey and his colleagues have devised a theoretical means to stop light using what are known as metamaterials, or materials whose properties depend on their structure and not the composition of the material.
